Aerial whistle
Discussion
Elise S2 111s '03
At over 75mph by far the loudest thing about my car (even with a sports exhaust) is the whistle from the radio aerial (mounted on the engine cover). It makes motorway journeys 'less enjoyable'. I haven't measured it but i'd guess its about 6 inches long and doesn't look too big and I assume is original. Radio reception is normally pretty bad, don't know if getting a shorter one would make this notably worse - has anyone had similar issues and done anything successful about it?
I believe that newer S2's have a built in aerial in front clam, which presumably is to get around this problem but don't want to resort to that.

Mine doesn't seem to do it.
The standard aerial is significantly longer than six inches; probably over a foot. If it's the original, it should be by some margin the highest point on the car (see: http://www.elises.co.uk/models/s2/outline_side_t.j... ).
Reception is always pretty shocking I think.

On mine the door windows and seals have a small gap and I guess the whistling sound is caused by that.
I've started a few threads on radio reception in the past so search the archives. The MFRU emits a load of RFI. I grounded this with some kitchen foil and greatly improved the reception. I've never seen this mentioned anywhere else so I guess I discovered it

Is your whistling aerial just plain & straight or does it have a spiral on the surface along the length of it? If it doesn't have the spiral type then that might be the problem, apparently the spiraly design should stop the whistling.At over 75mph by far the loudest thing about my car (even with a sports exhaust) is the whistle from the radio aerial (mounted on the engine cover).

Recon MiniDiva could be right my S1 had a spiral type arial and I never had any whistling problems.You might be able to buy a replacement from halfrauds or maplin fairly cheaply - i think they just screw into the base that is mounted on the engine cover.
I learned of the spirally business when I had my Mini cooperS a few years ago as they have them fitted - a very nice salesman told me all about it!
